Benefits of technology

The present invention is about a new golf club head design that removes excess material from the back of the club head to improve its performance. This allows for a bigger club head, a bigger sweet spot, and a more optimal center of gravity. The new design also has a cavity back and a deep undercut, which helps to increase the club head's moment of inertia. An insert can be added to fill the cavity and improve the feel and playability of the club. Overall, this new design provides a more forgiving and effective golf club.

Problems solved by technology

Most of the material beyond what is required to maintain structural integrity can be considered parasitic when it comes to designing a more forgiving golf club.
Separating the recess from the cavity precludes the possibility of any material becoming lodged therein, which may have an adverse effect.

Embodiment Construction

[0022]Other than in the operating examples, or unless otherwise expressly specified, all of the numerical ranges, amounts, values, and percentages, such as those for amounts of materials, moments of inertias, center of gravity locations, and others in the following portion of the specification, may be read as if prefaced by the word “about” even though the term “about” may not expressly appear with the value, amount, or range. Accordingly, unless indicated to the contrary, the numerical parameters set forth in the following description and claims are approximations that may vary depending upon the desired properties sought to be obtained by the present invention. At the very least, and not as an attempt to limit the application of the doctrine of equivalents to the scope of the claims, each numerical parameter should at least be construed in light of the number of reported significant digits and by applying ordinary rounding techniques.

[0023]Notwithstanding that the numerical ranges...

Abstract

A golf club head having a deep undercut is disclosed and claimed. The club head includes a cavity in a back portion thereof, opposite the striking face. A recess is provided in the back portion of the club head in proximity of the heel and, optionally, the sole. The recess may extend to the hosel bore, and may be separate from the cavity. An insert, such as a dampening member or a weight member, may be positioned within the recess. The recess and any insert provided therein alter the club head moment of inertia and center of gravity location, providing an improved feel to the golf club.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention relates to a golf club. In particular, the present invention relates to a golf club head having a deep undercut.[0003]2. Description of the Related Art[0004]Golf club heads come in many different forms and makes, such as wood- or metal-type, iron-type (including wedge-type club heads), utility- or specialty-type, and putter-type. Each of these styles has a prescribed function and make-up. The present invention relates to golf club heads that have a predominantly solid material area located near the heel of the club head.[0005]Iron-type and utility-type golf club heads generally include a front or striking face, a hosel, and a sole. The front face interfaces with and strikes the golf ball. A plurality of grooves, sometimes referred to as “score lines,” is provided on the face to assist in imparting spin to the ball. The hosel is generally configured to have a particular look to the golfer, to provid...
